How To Replace Water Sensor Battery

The Water Sensor takes one Duracell CR-2032 Lithium 3V battery and has a life expectancy of up to 5 years depending on placement and usage.

To change your Water Sensor battery, twist the bottom and top apart and replace the battery inside. To close it again, make sure that the grooves are aligned before twisting it shut.

If your sensor is still offline after replacing the battery, skip to the section below for troubleshooting steps.
